' IMPROVEMENT IN COIN-COUNTERS.

Specication forming part of Letters Patent No. 183,833, dated October31, 1876; application filed September 9, 1876.

To all whom it may concern:

Be it known that I, ARON BERNsTErN, of Berlin, Prussia, in the Empire ofGermany, have invented a new and useful Improvement on Apparatus forSeparating False and Light Gold Coins, `of which the following is aspeciflcation:

This apparatus has for its object to provide the public with a simpleand convenient means of testing, in quick and automatic manner, thegenuineness and correct weight of every gold coin received, withouthaving recourse to goldscales, which occasion loss of time and disclosea feeling of distrusttoward customers and others, and are, for thisreason, but little employed in ordinary business.

The apparatus furnishes a reliable means to instantly detect any falseor light gold coin without showing the mode or mechanism by which thesame is tested, so that thereby the business man is protected againstlosses arising from this source.

This object is obtained in the present apparatus by allowing the goldcoin to fall through a narrow openin g and guide-channel onto a balanceor tilter, from which it will, if genuine and of full weight, roll atonce, by suitable deviatin g mechanism, into the cash box or receptacle;

-but if it is not genuine, or of short weight, it is conducted into. aseparate open receptacle, so as to indicate directly the lack ofgenuineness 0r full weight.

The apparatus may be arranged for gold coins of one, two, or moredifferent denominations-as, for instance, for ten and tive dollar goldpieces, or to English, French, or German coins, the apparatus beingreadily adapted and adjusted for either monetary mint.

As the parts of the apparatus adapted for smaller or larger` coins aresimilar to each other, differing merely slightly in dimensions, it isonly necessary to describe one part of the apparatus, the others beingmore or less identical in construction.

In the accompanying drawing, Figurel represents a top View, and Figs. 2and 3 are vertical longitudinal and transverse sections, respectively,on line x a: and y y, Fig. 1, of my improved apparatus for separatingand detecting false and light gold coins.

Similar letters of reference indicate corresponding parts.

In the drawing, A A are two or more narrow openings or slots, that arepreferably arranged in the counter, table, or other article, below whichthe apparatus is disposed for the purpose of being ont of sight. Theopenings A are of such width and length as to correspond exactly to thethickness and diameter of the dii'erent gold coins in use. The gold coinis dropped through the opening A, and passed along a verticalguide-channel onto an inclined plane, B, along which it will roll,between guide-arms D, to a balanced plate or piece of metal, G. Thisplate C forms part of a balance, which is, however, not hung steadilyand evenly,as usual in balances, but which is supported by across-lever, a, in uneven manner, so that the center of gravity issituated higher than the two hypomochlions b of the cross-lever. Thisbalance may therefore more properly be called a tilter.77 On the armopposite the plate C is placed a weight, C', that is adjustable on thethreaded arm to such a nicety that a gold coin of proper weight, when itrolls over the plate C, is enabled to depress the tilter; but, on theother hand, a gold coin of too light weight, or a false coin of anothermetal with less specific gravity, would pass over the tilter withoutoperating the same.

Any other false coin-for instance, one of an alloy of lead-having thecorrect weight would of necessity be oi' greater size than the openingA, and be thus detected even before being passed into the apparatus.

The required movement of the tilter is adjusted between set-screws d,that bear on the main lever of the same. The coin passes over thetilting plate C, between the guide-arms D, which are curved outwardly atthe ends to a vane or wing-plate, E, that swings on a vertical pivot-rodon top and bottom bearings e, adjustable by screws. The verticalpivot-rod of the vane E is provided with a crank-pin, f, that isconnected by a lever-rod, f', with an upright arm, g, that is fastenedto the crosslever or axis c of the tilter, so as to produce the swingingof the vane when the plate() is depressed by the passage of afull-weighted coin. A light or false coin will not operate the tilterand vane, and therefore leaves the vane in the position shown in fulllines in Fig. 1. A full- Vweighted coin depresses the tilter and swingsthe vane into the position shown in dotted lines in Fig. 1, passingalong the vane, and dropping directly into the cash box or receptacle F.A light or false coin does not move the vane from its normal position,and is therefore conducted along the same, over an inclined spout, F, toa suitable receptacle for false coins, which receptacle is preferablyopen, so as to indicate instantly the presence of a defective coin, andadmitof its being taken out and handed back to the party that presentedit for payment.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. An apparatus for separating and detecting lightand false gold coins, consisting, mainly, of conducting-channels, atilting mechanism, and a swinging vane or wing operated thereby, andexit spouts, substantially in the manner and for the purpose set forth.

2. rEhe combination, with the drop-opening A and guide-channels B D, fofan adjustable balance or tilter that is only depressed by a coin of fullweight, substantially as described.

3. The combination, with a tilting balance, of a swinging vane thatisoperated by the depression of the tilter 'by the gold coin,substantially as set forth.

4. The combination of the fulcrum-lever a of the tilter with arm g,lever-rodf, crankpin f, and vertically-pivoted vane E, substantially asdescribed. y v v 5. The guide-arms D, having curved outer ends, iucombination with the vane E, swinging against either end, to conduct thecoin without obstruction to the proper receptacle, substantially as setforth. I

InV testimony whereof I have, signed my name to this specification inthe presence of two subscribing witnesses.. i
